Abstract

A cone-shaped lens is integrally formed with a lateral member using a common material. The cone-shaped lens has a light-output surface having a corresponding area while the aforementioned member has an exterior same-side surface area that extends beyond the light-output surface by an amount that is at least four times the corresponding area of the cone-shaped lens'"'"'s light-output surface.

Claims

1. An apparatus comprising:

a cone-shaped lens formed of a material and having a light-output surface having a corresponding area extending along a first plane, the light-output surface having a first optical diffusivity;

a lateral member that is formed integral to the cone-shaped lens of the material, wherein the lateral member has an exterior front-side surface area that extends along the first plane beyond the light-output surface and that has a periphery configured to physically engage and visually occlude a front edge of a corresponding housing when the lateral member is installed with respect to the housing, the lateral member having a second optical diffusivity that is more diffuse than the first optical diffusivity such that the lateral member is translucent.

2. The apparatus of claim 1 wherein the lateral member comprises a substantially-planar member.

3. The apparatus of claim 2 wherein the substantially-planar member is substantially perpendicular to a longitudinal axis of the cone-shaped lens.

4. The apparatus of claim 1 wherein the lateral member extends outwardly from the cone-shaped lens on all sides of the cone-shaped lens.

5. The apparatus of claim 1 wherein the cone-shaped lens is substantially centrally located within the lateral member.

6. The apparatus of claim 1 wherein the periphery has a portion that is thicker than a non-peripheral part of the lateral member.

7. The apparatus of claim 6 wherein the portion that is thicker diffuses light differently than the non-peripheral part of the lateral member.

8. The apparatus of claim 7 wherein the portion that is thicker is less transparent than the non-peripheral part of the lateral member.

9. The apparatus of claim 6 wherein the non-peripheral part is recessed within the periphery of the lateral member.

10. The apparatus of claim 1 further comprising:

a housing configured to engage and hold the lateral member in an installed position.

11. The apparatus of claim 10 further comprising:

at least one light source disposed within the housing such that the at least one light source is optically engaged with the cone-shaped lens when the lateral member is installed with respect to the housing.

12. The apparatus of claim 11 wherein the light source comprises a light-emitting diode.

13. The apparatus of claim 12 wherein the housing comprises a heat sink configured to transfer heat exuded by the light-emitting diode.

14. The apparatus of claim 13 wherein the heat sink comprises a plurality of heat sink fins configured to transfer heat exuded by the light-emitting diode.

15. The apparatus of claim 13 wherein the heat sink is at least substantially comprised of metal.

16. The apparatus of claim 15 wherein the metal comprises aluminum.

17. The apparatus of claim 1 further comprising:

a plurality of posts formed integral to the lateral member of the material and being configured to couple the lateral member to the housing to thereby install the lateral member with respect to the housing and to also position the cone-shaped lens with respect to a light source that is disposed within the housing.

18. The apparatus of claim 1 further comprising:

a gasket disposed between the lateral member and the housing when the lateral member is installed with respect to the housing.

19. The apparatus of claim 18 wherein the gasket is disposed on a ridge around the lateral member.

20. The apparatus of claim 18 wherein the gasket is formed in place using a liquid adhesive.

21. The apparatus of claim 1 further comprising:

at least one additional cone-shaped lens formed of the material and that is also formed integral to the lateral member.

22. The apparatus of claim 21 wherein the at least one additional cone-shaped lens physically intersects the cone-shaped lens.

23. The apparatus of claim 22 wherein the cone-shaped lens and the at least one additional cone-shaped lens share, at least in part, the light-output surface.

24. An apparatus comprising:

a cone-shaped lens formed of a material and having a primary light-output surface having a corresponding area extending along a first plane, the primary light-output surface having a first optical diffusivity;

a lateral member that is formed integral to the cone-shaped lens of the material, wherein the lateral member has an exterior front-side surface area that extends beyond the primary light-output surface along the first plane by an amount that is at least four times the corresponding area of the cone-shaped lens'"'"'s primary light-output surface, the lateral member having a second optical diffusivity that is more diffuse than the first optical diffusivity such that the lateral member is translucent.

25. The apparatus of claim 24 wherein the exterior surface area is at least six times the corresponding area of the cone-shaped lens'"'"'s light-output surface.

26. The apparatus of claim 24 wherein the exterior surface area is at least eight times the corresponding area of the cone-shaped lens'"'"'s light-output surface.

27. The apparatus of claim 24 wherein the lateral member extends outwardly from the cone-shaped lens on all sides of the cone-shaped lens.

28. The apparatus of claim 24 wherein the cone-shaped lens is substantially centrally located within the lateral member.

29. The apparatus of claim 24 wherein the periphery has a portion that is thicker than a non-peripheral part of the lateral member.

30. The apparatus of claim 29 wherein the non-peripheral part is recessed within the periphery of the lateral member.

31. The apparatus of claim 24 further comprising:

a housing configured to engage and hold the lateral member in an installed position.

32. The apparatus of claim 31 further comprising:

at least one light source disposed within the housing such that the at least one light source is optically engaged with the cone-shaped lens when the lateral member is installed with respect to the housing.

33. An apparatus comprising:

a cone-shaped lens having a apex that is designed to accept light from a light emitter and having only one primary light-output surface formed at the base of the cone with a corresponding area extending along a first plane, the primary light-output surface having a first optical diffusivity;

a lateral member that is formed integral to the cone-shaped lens of the material and having a second optical diffusivity that is more diffuse than the first optical diffusivity such that the lateral member is translucent, wherein the lateral member has an exterior same-side planar surface area extending along the first plane that is at least four times greater than the corresponding area of the cone-shaped lens'"'"'s primary light-output surface.
